DROUGHT AND FINE FUEL MOISTURE CODE EVALUATION: AN EARLY WARNING SYSTEM FOR FOREST/LAND FIRE USING REMOTE SENSING APPROACH

摘要

This study has evaluated two parameters of Fire Danger Rating System (FDRS) using remote sensing data i.e. Drought Code (DC_s) and Fine Fuel Moisture Code (FFMC_s) as an early warning program for forest/land fire in Indonesia. By using the reference DC (DC_obs) and FFMC (FFMC_obs) from weather station was calculated the value of accuracy, bias and error from DC_s and FFMC_s. The results show that FFMC_s have fairly high correlation with FFMC_obs (r = 0.68, bias = 7.6, and RMSE = 15.7 points), while DC_s has a better correlation (r = 0.88, bias = 49.91, and RMSE = 80.22 points). Fluctuations FFMC_s and DC_s value shows similar pattern of DC_obs and FFMC_obs value. Nevertheless, FFMC_s and DC_s show an overestimation value than that FFMC_obs or DC_obs, particularly during dry season. In this study also indicated that DC_s and FFMC_s can describes fire occurrence within a period of 3 months before fire occur, particularly for DC parameter. These results demonstrate that remote sensing data can be used for monitoring and early warning fire in Indonesia as a complementary of observation data.
